3 BACKGROUND

3.1 Field of the Invention

This invention relates to wireless telecommunication. In particular, the various embodiments of the invention relate to monitoring and tracking wireless communications devices and their activities, the construction and management of applications for performing such functions, the monitoring of activities and data stored in mobile devices, and the transparent exfiltration of collected information from monitored mobile devices using wireless links. The present invention has applications in fields of computer science, electronics, telecommunications, and security.

3.2 The Related Art

Mobile devices include pagers, mobile phones, and combination devices that include the functionality of mobile phones, pagers, and personal digital assistants (PDAs). These devices allow the exchange of textual information (e.g., using pagers, cell phones, or PDAs) as well as voice and data (e.g., using cell phones and PDAs). Mobile devices have also recently been integrated with useful features such as global positioning system (GPS) access, cameras, and scanners (including scanners able to process radio frequency identification (RFID) and barcodes), and magnetic data storage cards. Wireless communication (“wireless”) allows two or more electronic devices to exchange information without the need for a physical connection (i.e., a wire or cable) between the devices, using radio or microwave transmissions; and devices using wireless communications can be fixed or mobile. Unlike traditional “wired” technologies, wireless communication technologies permit users to operate from any location at which there is sufficient wireless signal power to enable the communication. Fixed wireless devices allow wireless communication from a fixed location to mobile device. Mobile wireless permits communication between several mobile devices; and mobile devices generally communicate using radio-frequency transmissions.

Transmitters send a signal from a wireless communication point-of-presence to a mobile device, while receivers process a signal received at a point-of-presence from a device. A point-of-presence is a collection of one or more transmitters and receivers that can communicate with a mobile device. For example, a fixed point-of-presence can be a communication tower in a cellular telephone network or a wireless local area network connection at a coffee shop. Fixed points-of-presence are typically spaced so that their ranges overlap to allow continuous communication as a device moves amongst various locations. A mobile point-of-presence can be any other mobile device that is not a fixed point of presence. An example of a mobile point of presence is a laptop accepting WiFi connections or a mobile telephone handset accepting WiFi or Bluetooth. As long as a connection can be made between the point-of-presence and the mobile device, information can be sent and received appropriate to the capabilities of the device. But in many environments, such constant contact between a mobile device and a point-of-presence is not possible; because areas exist which are not in range of a point-of-presence, and variances of land or building materials may interfere with the signal. As a result, a mobile device can be out of coverage for a few minutes or hours, and mobile phone calls, wireless internet connections, and access to mobile points of presence may be cut off unexpectedly.

More recently, mobile devices have allowed application programs to be written to manage data communication (and not just voice) to and from the device so that more advanced functionality can be enabled in the device without connecting the mobile device to a computer or other device to download and install the application programs. Such applications can communicate with other devices, such as networked computers and other electronic equipment (including other mobile devices). Examples include the ability to send and receive email; review and process calendar, tasks, contacts, and other personal information manager records; retrieve, display and manage stock data; find and display nearby restaurants or clothing stores; and to receive or send documents and files using a mobile device. Alternatively, these applications rely upon an always-available Internet connection, and communicate using standard Internet techniques and protocols (for example, sockets, UDP (User Datagram Protocol), TCP (Transmission Control Protocol), and HTTP (HyperText Transfer Protocol)). In some cases, applications make use of WAP protocols and associated WAP Gateways to access Internet resources when the device's display resolution or other capabilities are inadequate for full Internet access. Wireless Application Protocol (WAP) is a standard implemented through WAP Gateways which are servers that act as communications bridges between wireless devices and internet services, transferring data between devices and services, and transforming data as required between the various protocols used. Each of these methods relies on the wireless connection being available when needed.

A user's employment of a mobile device, and the data stored within a mobile device, is often of interest to individuals and entities that desire to monitor and/or record the activities of a user or a mobile device. Some examples of such individuals and entities include law enforcement, corporate compliance officers, and security-related organizations. As more and more users use wireless and mobile devices, the need to monitor the usage of these devices grows as well. Monitoring a mobile device includes the collection of performance metrics, recording of keystrokes, data, files, and communications (e.g. voice, SMS (Short Message Service), network), collectively called herein “monitoring results”, in which the mobile device participates. Network management applications monitor device performance in order to identify network and device performance issues. Additional applications of monitoring technologies include the protection of corporate information and ensuring information covered by non-disclosure agreements is not inappropriately distributed. For example, recent high profile securities fraud cases have identified users who have sent details of upcoming mergers and acquisitions to accomplices who use the information for personal profit. Similarly, monitoring technologies provide advantages to law enforcement as the criminal element increasingly uses portable mobile devices to communicate and manage their criminal enterprises.

Mobile device monitoring can be performed using “over the air” (OTA) at the service provider, either stand-alone or by using a software agent in conjunction with network hardware such a telephone switch. Alternatively, mobile devices can be monitored by using a stand-alone agent on the device that communicates with external servers and applications. In some cases, mobile device monitoring can be performed with the full knowledge and cooperation of one of a plurality of mobile device users, the mobile device owner, and the wireless service provider. In other cases, the mobile device user or service provider may not be aware of the monitoring. In these cases, a monitoring application or software agent that monitors a mobile device can be manually installed on a mobile device to collect information about the operation of the mobile device and make said information available for later use. In some cases, this information is stored on the mobile device until it is manually accessed and retrieved. In other cases, the monitoring application delivers the information to a server or network device. In these cases, the installation, information collection, and retrieval of collected information are not performed covertly (i.e. without the knowledge of the party or parties with respect to whom the monitoring, data collection, or control, or any combination thereof, is desired, such as, but not limited to, the device user, the device owner, or the service provider). The use of “signing certificates” to authenticate software prior to installation can make covert installation of monitoring applications problematic. When software is not signed by a trusted authority, the software may not be installed, or the device user may be prompted for permission to install the software. In either case, the monitoring application is not installed covertly as required. Additionally, inspection of the mobile device can detect such a monitoring application and the monitoring application may be disabled by the device user. Alternatively, OTA message traffic may be captured using network hardware such as the telephone switch provided by a service provider. This requires explicit cooperation by the service provider, and provides covert monitoring that is limited to message information passed over the air. As a result, service provider-based monitoring schemes require expensive monitoring equipment, cooperation from the service provider, and are limited as to the types of information they can monitor.

Additional challenges are present when the monitoring results are transmitted from a mobile device. First, many mobile devices are not configured to transmit and receive large amounts of information. In some instances, this is because the mobile device user has not subscribed to an appropriate data service from an information provider. In other instances, the mobile device has limited capabilities. Second, transmitting information often provides indications of mobile device activity (e.g. in the form of activity lights, battery usage, performance degradation). Third, transmitting information wirelessly requires operation in areas of intermittent signal, with automated restart and retransmission of monitoring results if and when a signal becomes available. Fourth, many mobile devices are “pay as you go” or have detailed billing enabled at the service provider. The transmission of monitoring results can quickly use all the credit available on a pre-paid wireless plan, or result in detailed service records describing the transmission on a wireless customer's billing statement. Lastly, stored monitoring results can take up significant storage on a mobile device and the stored materials and the use of this storage can be observed by the device user.

Some devices have a removable identity card. SIMs are part of a removable smart card, and the combination of a SIM and the smart card is commonly referred to as a “SIM card”. SIM cards securely store the service-subscriber key used to identify a subscriber to a given wireless network, and they also support the SIM Application Toolkit (STK), which is a standard of the GSM system that enables the SIM to initiate actions that can be used for various value added services, such as payment authorization for purchases. In GSM 2G networks, the STK is defined in the GSM 11.14 standard. In GSM 3G networks, the USIM Application Toolkit (USAT) is the equivalent of STK, and is defined in standard 3GPP 31.111. Both STK and USIM are referred to herein as “STK” when the context does not require specification of the 2G or 3G versions specifically.

The STK consists of a set of functions programmed into the SIM card that define how the SIM can interact directly with the device (commonly referred to in this context as a “handset”), and/or the network. The STK provides functions that can give commands to the handset, for example: to display a menu and ask for user input, to dial phone numbers, or to control or access other device features, such as GPS receivers and RFID readers. These functions enable the SIM to carry out an interactive exchange between a network application and the end user and to provide or control access to the network. Details of STK capabilities and use are defined in the 3rd Generation Partnership Project (3GPP) Specification of the SIM Application Toolkit (STK) for the Subscriber Identity Module-Mobile Equipment (SIM-ME) interface (also known as the 11.14 specification) and related standards documents.

In addition to the STK, SIM cards can implement additional systems for supporting application programs that run on the SIM card. There are a plurality of systems and standards for such support, including the Open Platform and Java Card standards. Some standards support only one operating system or hardware smart card, others, like the Java Card standard, are supported on a plurality of smart cards under a plurality of operating systems. These systems can provide mechanisms for installing applications programs, selecting applications to execute, and means for the application programs to interact with each other or with the world outside of the smart card they are running on. Thus, the open-ended capabilities of applications installed on smart cards pose a potential security hazard to the smart card and to devices in which the cards are installed, similar to that of other general purpose computing devices.

Although SIM cards originated with GSM devices, the cards have proven so useful that other network types have adopted similar mechanisms. For example, CDMA systems have implemented a SIM-like device called a Removable User Identity Module (R-UIM), and a more advanced version of this called a CDMA Subscriber Identity Module (CSIM), which are cards developed for CDMA handsets that are equivalent to a GSM SIM. The CSIM is physically compatible with GSM SIMs, can fit into existing GSM phones, and is an extension of the GSM standard but is capable of working on both CDMA and GSM networks.

Removable identity modules can designate one or more pieces of software to run when a device is powered on with the identity modules. Removable identity modules thus provide a mechanism for surrupticiously installed software to be installed and then moved between devices.

From the foregoing, it will be appreciated that effective covert monitoring of a mobile device requires the combination of several technologies and techniques that hide, disguise, or otherwise mask at least one aspect of the monitoring processes: the covert identification of the mobile devices to be monitored, the covert installation and control of the monitoring applications, and the covert exfiltration of collected monitoring results. As used herein, “covert exfiltration” refers to a process of moving collected monitoring results from a mobile device while it is under the control of another without their knowledge or awareness. Thus covert exfiltration processes can be those using stealth, surprise, covert, or clandestine means to relay monitoring data. “Collected monitoring results” as used herein includes any or all materials returned from a monitored mobile device to other devices, using either mobile or fixed points-of-presence. Examples of collected monitoring results include one or more of the following: command results, call information and call details, including captured voice, images, message traffic (e.g. text messaging, SMS, email), and related items such as files, documents and materials stored on the monitored mobile device. These materials may include pictures, video clips, PIM information (e.g. calendar, task list, address and telephone book), other application information such as browsing history, and device status information (e.g. device presence, cell towers/wireless transmitters/points-of-presence used, SIM data, device settings, location, profiles, and other device information). Additionally, the capability to covertly utilize a mobile device as a covertly managed camera or microphone provides other unique challenges.

Thus covert monitoring of a mobile device's operation poses the significant technical challenges of hiding or masking the installation and operation of the monitoring application, its command and control sessions, hiding the collected monitoring results until they are exfiltrated, surreptitiously transmitting the results, and managing the billing for the related wireless services. The exemplary illustrative technology herein addresses these and other important needs.

FIG. 1 illustrates an exemplary mobile device monitoring and control architecture in accordance with one embodiment of the present invention, in which a first monitored mobile device communicates with a control system to provide device monitoring and management features under the control of the control system. The exemplary mobile device monitoring architecture comprises a control system (1400), which further includes a control service (1410), a module repository (1420), an exfiltration data service (1430), a listen-only recording service (1440) and a WAP Gateway (1450), each of which is connected through one or more wireless networks (e.g. 1200 a) such as a cellular network or other wireless network such as a WiFi (802.11b/g) wireless network (e.g. 1200 b) to any of a plurality of monitored mobile devices (e.g. 1100 a, 1100 b), through a computer implemented device controller (1490) as described in greater detail below. Implementation of these elements can be accomplished by those having ordinary skill in the art.

Continuing with reference to FIG. 1, the Figure also illustrates a wireless communication system architecture (1000) in which a first monitored mobile device (1100 a) communicates with a computer implemented device controller (1490) in accordance with one embodiment of the invention. A monitored mobile device (1100 a, 1100 b) is capable of connecting to wireless telephony networks and associated wireless data networks, and can comprise devices such as cell phones, PDAs, handheld or laptop computers with cellular modems, and are described in more detail below and with reference to FIG. 2. Each monitored mobile device (1100) communicates through one or more wireless communications networks (e.g. 1200 a, 1200 b) that each include a gateway (1210 a, 1210 b) that is in communication with a computer network (1300). Some examples of wireless communications networks (1200 a and 1200 b) include cellular telephone networks utilizing CDMA (Code Division Multiple Access) or GSM (Global System for Mobile communications) technologies, and wireless metropolitan or area networks utilizing 802.11-based technologies. The wireless communication networks enable the wireless transmission and reception of information between mobile devices and external systems. Wireless communications can provide, in addition to voice telephony communications, data communications capability, such as TCP/IP-based protocol support, or more limited data communications means using SMS, MMS, FLEX, and other messaging protocols. Additionally, wireless communications can involve communications using peer to peer communications mechanisms, such as Bluetooth, and can even provide hybrid communications using one or more of the above communications means simultaneously or sequentially. Exemplary wireless communications networks (1200 a, 1002 c, and 1200 c) are composed of components having designs, materials, and methods well known to those of ordinary skill in the art.

The network (1300) provides communication with a device controller that is in communication with one or more services or servers, and at least a first monitored mobile device (1100).

The control system (1400) further comprises one or more instances of services hosted on one or more computer systems, commonly called services. Each service may be operated on a computer, which is commonly called hosting. Each service is hosted on a single computer or alternatively, instances of each service can be hosted on several discrete computers. Further alternative configurations can provide for several different services to be hosted on a single computer.

The device controller (1490) of the control system (1400) provides communications support and routing selection between each particular monitored mobile device and server components such as a control service (1410), a module repository (1420), an exfiltration data service (1430), a listen-only recording service (1440) and a WAP Gateway (1450). Components (1400, 1410, 1420, 1430, 1440, 1450 and 1490) can be integrated into a single component, or implemented as one or more separate server devices and database components as shown in FIG. 1. The device controller (1490) selects one or more communications networks and methods for communicating between a particular monitored mobile device and one or more service components. The selection can be made upon a variety of factors and may be made automatically or under control of a person operating the device controller. Some factors that may be used by the device controller in the selection process include the device ID, device OS, device status, network availability, network device user configuration, network carrier configuration, version and capabilities of software on the monitored mobile device, and the instructions of the control system operator. In a first exemplary embodiment, the device controller (1490) can select an SMS communication link using a commercial cellular telephone network, such as those provided by commercial service providers like Verizon or AT&T/Cingular. In a second exemplary embodiment, the device controller (1490) can select a TCP/IP communications link using a wide area wireless network such as metropolitan wireless network such as those provided by Earthlink or MetroFi. In some exemplary embodiments the device controller (1490) can select a plurality of communication links and permit the selective router module (2320) on the monitored device to choose between them as detailed below.

The device controller (1490) provides networking infrastructure that permits each service to communicate with one or more monitored mobile devices (1100) using one or more communications networks and protocols as described above. The device controller (1490) can be integrated into each service, or can be structured as one or more additional components. The device controller (1490) can optionally switch between wireless networks, communication protocols, and can split or assemble communications from partial communications using disparate networks. For example, a device controller (1490) can use SMS to communicate with a monitored mobile device (1100) when its status is not known, and switch to communications on an 802.11 WiFi link when a monitored mobile device (1100) is known to be in range of an 802.11 wireless network. Additionally, a device controller (1490) can break a larger message into smaller parts, referred to as fragments, and communicate these fragments over protocols that are not capable of communicating the entire message in one piece. The device controller (1490) also can receive message fragments from a monitored mobile device and “reassemble” them into complete messages for processing by a service.

Additionally, the device controller (1490) can be configured to determine an appropriate way to reach a specific monitored mobile device using a combination of state information and routing information. Thus, as a monitored mobile device moves from being only reachable on a cellular network, to being reachable on a higher bandwidth 802.11 based wireless network, to being reachable using a peered device as a proxy or gateway, to being completely inaccessible, the device controller (1490) can consolidate this information and provide a common means for most efficiently reaching the monitored mobile device (1100).

The device controller (1490) also can provide message encryption/decryption, determine device status based upon periodic reporting (e.g. heartbeat), and other services as will be described in further detail below.

Services (1410, 1420, 1430, 1440 and 1450) preferably communicate with each monitored wireless mobile device (1100 a, 1100 b) using the device controller (1490) as described above. Alternatively, the services can communicate directly with a monitored wireless mobile device. Direct communication with a monitored wireless mobile device means communicating with the monitored mobile device (1100) using a well-known protocol such as TCP/IP in the case of wireless networks (such as 802.11 networks) using common networking protocols. In telephony based networks such as CDMA or GSM networks, direct communications with a monitored wireless mobile device means communicating with the telephony network provider's network interface using a well known protocol, and having the network interface communicate with the monitored wireless mobile device on the service's behalf using a telephony protocol. In the illustrated example, services include specific applications in the form of an exfiltration Data Service (1430) a Control Service (1410), a Module Repository Service (1420), a Listen-Only Recording Service (1440) and a WAP Gateway, each of which in turn pass data to, and receive data from, a monitored mobile device with a monitoring component (“monitored mobile device client,” 1120 a/b). The monitored mobile device client (1120 a/b) also can serve as a filter between network traffic and the applications (1110 a/b/c/d) running on the monitored mobile device (1100).

Although FIG. 1 illustrates a mobile device for illustrative purposes, the term “mobile device” will be defined herein to include not only traditional mobile devices including pagers and cellular telephones, but also terminal devices, emulated devices, and server devices connected to at least one wireless network. Aspects of the exemplary, illustrative technology are equally applicable to all classes of devices that experience intermittent connectivity, such a laptops and PDAs that are intermittently connected to a company LAN. In addition, although FIG. 1 shows communication between a service (e.g., a server contained within the network (1300) or within the device controller (1490)) and a particular monitored mobile device (e.g., 1100 a) it will be appreciated by those of ordinary skill in the art that an arbitrary number of devices can communicate with each other in accordance with the technology as described herein. Thus, the exemplary illustrative technology herein includes communications among all types of devices.

6.2 Module Repository 1420

The module repository (1420) is, in some embodiments, a server device hosting the module repository (1420) service. In such embodiments, the module repository (1420) service stores and manages monitored mobile device modules, selects modules for deployments, provides installer packages and configurations for specific monitored mobile devices (1100), and manages known monitored mobile device type-module associations. The module repository (1420) can be constructed using a network appliance or server computer running one of the server operating systems well known to those skilled in the art.

The module repository (1420) maintains a database of modules (described below) and manages a list of associations between specific types of monitored mobile devices (1100) and modules that can be used on those monitored mobile devices (1100). Types of monitored mobile devices can be further categorized by the operating system used, the communication service provider used by the device, or by other relevant factors as determined by those of skill in the art. Operating systems and other relevant factors can be further categorized, such as by version numbers or options installed. The modules themselves can be taken from a database, a directory, shared files, or other storage means known to those skilled in the art. In some embodiments, groups of modules can be grouped together by the module repository (1420). The database of modules provides a mechanism for identifying modules that may be associated with a particular monitored mobile device (1100), network provider, or other attribute.

In one embodiment, the module repository (1420) maintains a database of tags associated with each module stored in the system. The database of tags identifies a specific monitored mobile device or device type (1100), operating system, and control function provided by a module. A selection of modules that include a set of well-known tags can be selected from the database using well-known query techniques. For example, a query can be constructed to search for all modules with a minimum set of tags. One such example query might be constructed for a “Blackberry 1710” monitored mobile device (1100) and would be for all modules that have a “Device=Blackberry 1710” tag. A more refined query might be for modules that have a “Device=Blackberry 1710” tag and an “OS=4.1” tag. The tag can take the form of a database entry, or can be contained within a digital signature certificate provided with the modules.

In other embodiments, a list of modules for each specific monitored mobile device (1100) or monitored mobile device configuration can be loaded into the module repository (1420). The module repository (1420) can use this list of modules to associate specific modules with a specific monitored mobile device (1100) of a known type. The list may be stored in a database, flat file, directory service, or other storage means (not shown).

The module repository (1420) uses information obtained from a device discovery and modification module (2310) in conjunction with the pre-defined association information, and desired control information, to construct a list of modules to be deployed to a monitored mobile device (1100), and to provide a distribution package for module distribution. Alternatively, an operator can assign a list of modules to be deployed to a monitored mobile device. The module(s) can be packaged using an appropriate packaging technology, for example, Microsoft cab and dll files for Windows, SIS files for Symbian, jar files for J2ME, or other packaging and distribution means appropriate for the destination mobile device. The module repository (1420) can encrypt the package using a common or device-specific key to protect the contents. In some embodiments, one or more modules can be pre-associated and delivered as a unit by the module repository (1420). FIG. 3 is a process flowchart that details the steps performed by the module repository (1420) to produce a package.

As can be seen in FIG. 3, in step 3110, the module repository (1420) receives monitored mobile device information (for example, one or more of device type, OS version, device ID, etc.) from either the control service (1410) or directly from a monitored mobile device (1100). In a first exemplary embodiment, the monitored mobile device information is stored in a device database and is made available to the module repository (1420) using that database. In a second example embodiment, the monitored mobile device information is provided directly to the module repository (1420) as part of the service call. In an even more particular embodiment, the monitored mobile device information is provided to the module repository (1420) as parameters to a URI provided as part of a service call to the module repository (1420).

In optional step 3120, the module repository (1420) receives control information indicating the monitored mobile device (1100) and the controls and modules to be deployed to the monitored mobile device (1100). The control information may include such information as the monitored mobile device (1100) ID and the desired controls and modules for the monitored mobile device (1100). In some exemplary embodiments, the control information is preconfigured within the device repository or within a database accessed by the module repository (1420). In other particular exemplary embodiments, the control information is provided to the module repository (1420) from another service, such as the control service (1410).

In step 3130, the module repository (1420) uses the monitored mobile device information and the control information to determine the specific modules to use for the device discovery and modification module (2310) and the control module (2340). Different monitored mobile devices (1100) can have differing requirements for the device discovery and modification module (2310) and control module (2340) based upon device-specific characteristics, such as monitored mobile device operating system (2100), configuration parameters, and the like. Differing modules can be provided in order to effectively manage and control modules installed to different configurations of monitored mobile devices.

In step 3140, the module repository (1420) uses the monitored mobile device information and the control information to determine the monitoring modules to use for the monitored mobile device (1100). Different monitored mobile devices have varying hardware configurations, such as cameras and available memory, and each piece of hardware can require differing modules. For example, it makes no sense to deploy an image capture module to a monitored mobile device (1100) that does not have an embedded image sensor (e.g. a camera). Module deployment packages appropriate to each known device type can be pre-built and stored for selection as needed, modules can be stored individually and assembled into a deployment package as needed, or a combination of these methods can be used for different device types, as determined to be appropriate by those having skill in the art.

In step 3150, the module repository (1420) selects or constructs a deployment package for the device discovery and modification module and control module(s) determined in step 3120. The deployment package can be as simple as a list of modules to be downloaded or a single file that contains multiple modules. The single file may be a single module, or may be an installer package as described above.

In some embodiments, the deployment package is protected for integrity using techniques such as digital signatures that are well known to those skilled in the art. Similarly, each deployment package can be optionally encrypted using either public key or symmetric key encryption. For example, a deployment package may be encrypted using a key specific to a mobile device, such as the mobile devices' device ID. Carrier and manufacturer device identification numbers are good candidates for potential keys.

Once a deployment package is selected or constructed, the module repository (1420) makes it available in a step 3160, referred to as “publishing.” Publishing the package makes the package available to monitored mobile devices (1100) and other services. In one particular embodiment, the deployment package is published to a service that makes it available to the monitored mobile device (1100) for download.

The process of selecting or constructing and publishing one or more deployment packages for the modules to be deployed to a monitored mobile device (1100) are repeated for the monitoring modules. These steps are shown in the flowchart as steps 3170 and 3180.

In the flowchart of FIG. 3, steps 3150 to 3180 are shown as discrete steps for clarity as to the functional aspects of the process. Without loss of generality, in some exemplary embodiments, steps 3150 and 3170 are combined for efficiency. Similarly, steps 3160 and 3180 may be combined for efficiency Similarly, steps 3150 to 3170 may be repeated as often as necessary, and can produce several deployment packages for a single monitored mobile device (1100). Likewise, once a deployment package, or packages, has been created for a particular device type, operating system or other relevant factors, the package(s) can be stored, for example, in a database, and used with a plurality of mobile device instances that match the device type, operating system or other relevant factors that the package was created for. This capability permits greater efficiency, and shortens deployment time.

In step 3190, the module repository (1420) notifies the device controller (1490) to initiate download of one or more packages to a monitored mobile device (1100).

Modules downloaded to a monitored mobile device will replace, modify, enhance, or otherwise alter the normal processing of one or more aspects of the device operating system or other typical software for purposes of implementing the technology herein. Where the device operating system or other software supports the concept of “loadable modules” (e.g. “dynamic loadable libraries (DLLs)”, “plug-ins”, or “drivers”), it can be possible to implement one or more of the downloaded modules in the form of loadable modules and incorporated into the monitored mobile device's systems using the facilities present in the device to support this mode of operation. In some cases it can be possible to replace the monitored mobile device's operating system in whole or in part with software that supports the monitoring and other aspects of the technology described herein in addition to providing the expected behavior in the monitored device from the point of view of the device's user, service provider, and other entities that are not involved in the monitoring and other activities of the technology described herein. In some cases the original device software can be retained and used in whole or in part to accomplish this, while not being allowed to regain full control over the monitored device.

6.3 Control Service (1410)

The control service (1410) provides command and control services to the control system (1400). The control service (1410) provides a database of devices currently being monitored, in which information about each monitored mobile device (1100) is stored. This information includes monitored mobile device identification information, such as IMEI (International Mobile Equipment Identity), IMSI (International Mobile Subscriber Identity), MIN (Mobile Identification Number), and ESN (Electronic Serial Number), along with assigned telephone number, monitored mobile device configuration information, such as the version of the operating system present on the monitored mobile device (1100), and monitored mobile device information such as device type, model, and device capabilities. For example, a device type and model can be used to identify the specific equipment being used at the monitored mobile device (1100). Device capabilities include the availability of GPS or camera functions on the monitored mobile device (1100). The database is also used to form associations between one or more monitored mobile devices (1100), such as identifying monitored mobile devices (1100) associated with one or more persons. The database thus provides the ability to look up and control a monitored mobile device (1100) if a user knows the identifying information or a person associated with the monitored mobile device (1100). Thus, the monitored mobile devices (1100) associated with a particular person (e.g. a particular user's three cellular telephones), or all of the cellular telephones belonging to a group of people (e.g. the cellular telephones of a particular group of interest), can be associated together. The ability to associate disparate monitored mobile devices (1100) provides a mechanism to provide common command and control to all of the monitored mobile devices (1100) that are so associated together in a group.

The control service (1410) also manages the status of each monitored mobile device (1100) known to it. The status of the each monitored mobile device (1100) defines whether the mobile device is currently online and available, the aspects of monitoring that the device is configured to support, and whether the monitored mobile device (1100) has uploaded all monitored information that has been collected. Other information collected in the status of the monitored mobile device (1100) includes whether a monitored mobile device (1100) is reporting information on schedule, current state of the mobile device and its security mechanisms (e.g. the device's ability to perform the monitoring functions covertly), and whether the mobile device is currently collecting monitoring (or not).

The control service (1410) is further able to issue commands to and monitor requests from the control component of the monitoring device client (1120). The control service (1410) preferably operates in conjunction with the other services, in particular, a device controller (1490), to send commands to and receive responses from monitored mobile devices (1120). The control service (1410) also monitors requests from monitored mobile devices (1100), including data exfiltration requests and module download requests. In some embodiments, the control service (1410) receives these requests and forwards them to another service for processing. In other embodiments, the control service (1410) receives notifications of the requests from the service processing the request.

The control service (1410) supports several commands related to monitoring mobile devices. Examples of such commands are listed in Table 1.

TABLE 1 Control Service Commands COMMAND FUNCTION Collect Device Requests device information from the network Information provider and/or monitored mobile device (1100). Obtains device information, including operating system version, device type, and device capabilities. Status update Requests a status update from the network providers and/or one or more monitored mobile device (1100). Install/uninstall Requests one or more monitored mobile device module (1100) to install/uninstall one or more particular modules. Start/stop Requests one or more monitored mobile device monitoring (1100) to start/stop specific aspects of monitoring. Start/stop Requests one or more monitored mobile device exfiltration (1100) to start/stop specific aspects of the exfiltration of monitoring results. Disable device Requests one or more monitored mobile devices (1100) to be disabled. Set Destination Sends the Device the specified URL for exfiltration information. This is set upon initial installation and canalso be updated after module installation Provisioning Allows for device settings to be updated or changed Device that creates the device runtime environment to be Settings most receptive to exploits

The control service (1410) manages and controls operations of other services of control system (1400). These services can be used to extend the range of commands and functions provided by the control service (1410).

The control service (1410) primarily communicates with other services using a combination of service interface calls and responses, direct application requests, and using various event-based mechanisms. For example, the control service (1410) may communicate with the exfiltration data service (1430) using a service-based interface to determine a list of monitoring results stored for a specific monitored mobile device (1100), and can further communicate with a notification service (not shown) in order to cause a specific user to be notified when new monitoring results have been received for a specific monitored mobile device (1100).

Lastly, the control service (1410) provides a user interface for managing monitored mobile devices, commands, and the command (results). In some embodiments, this is a web-based interface.

6.4 Exfiltration Data Service (1430)

The exfiltration data service (1430) receives, stores, and manages monitoring results exfiltrated from one or more monitored mobile devices (1100). The information is stored by the exfiltration data service (1430) as described below, and is preferably cross-referenced by source device information. In some embodiments, the exfiltration data service (1430) provides a file store in which exfiltration data is stored. In alternate embodiments, the monitoring results may be stored in a database or other content management system that is part of the exfiltration data service (1430). In some implementations, the exfiltration data service (1430) provides key management service to manage the encryption keys of encrypted monitoring results. Monitoring results can be encrypted (or re-encrypted) by the exfiltration data service (1430) in order to protect the monitoring results after they are received from a monitored mobile device (1100). Similarly, the exfiltration data service (1430) may digitally sign, or otherwise protect for integrity, monitoring results using techniques understood by those skilled in the arts. Protecting monitoring results in this manner preserves their usefulness as evidence when the system of the present invention is used by law enforcement personnel.

The exfiltration data service (1430) makes this information (monitoring results, key information) available to authorized users. The information can be provided using a dedicated user interface or as part of a service interface. In some embodiments, the exfiltration data service (1430) can send a notification to one or more services or users by sending an event, a service call, or by other means when a specific monitoring result is received and made available by the exfiltration data service (1430).

6.5 Listen-Only Recording Service (1440)

The listen-only recording service (1440) provides a telephone number, accepts a telephone call and a forwarding number from the monitored mobile device (1100), and forwards the call to the forwarding number, makes a recording, and sends the recording to a data repository (not shown).

When the user of the monitored mobile device attempts to place a call that requires monitoring, the monitored mobile device temporarily blocks the call from being placed, contacts the Listen-Only Recording Service (1440) to obtain a telephone number and to provide the Listen-Only Recording Service (1440) with the number the device user has attempted to call (the forwarding number). The monitored mobile device then places a call from the monitored mobile device to the number provided by the Listen-Only Recording Service (1440). The Listen-Only Recording Service (1440) places a call to the forwarding number, answers the call from the monitored mobile device and, for the duration of the call from the monitored mobile device, records the call and forwards the call to the forwarding number. In this way the monitored mobile device user obtains the expected call to the requested party, but the Listen-Only Recording Service (1440) is enabled to record the call for future use. In some exemplary implementations, the monitored mobile device's call log is adjusted to show that the call was placed to the originally requested number, rather than to the number provided by the Listen-Only Recording Service (1440). In some exemplary implementations the Listen-Only Recording Service (1440) provides the monitored mobile device's identifying information to the communication service provider when placing the call to the forwarding number so that the call is reflected as expected on the device user's account in order to maintain covertness and surreptitiousness of operations.

An alternative method of operation for the Listen-Only recording Service (1400) involves the monitored mobile device placing the originally requested phone call to the originally requested phone number, and including the Listen-Only Recording Service (1440) phone number in a conference call arrangement, so that the Listen-Only Recording Service (1440) is enabled covertly and surreptitiously to record the telephone call. In some exemplary embodiments, the monitored mobile device's call log is adjusted to show that the call was not placed as a conference call, and the call is placed in such a manner as to avoid conference call charges appearing on the device user's account using methods described herein. The methods used to place conference calls from wireless mobile devices are well understood by those having skill in the art.

When it is desired to record a call placed to a monitored mobile device, the monitored mobile device transmits the data to the exfiltration data service for storage, as with other gathered data. When possible, such exfiltration is done as the call occurs. Some devices, such as GSM phones, do not support concurrent voice and data connections. On such devices incoming and outgoing (mobile originated and mobile terminated calls) are recorded to device memory as audio files while the call is active. When the call is complete the recorded audio files are uploaded from the device's memory to the server. When the files have been confirmed as received by the server, the monitored mobile device deletes the recorded audio files from the device's memory.

6.6 WAP Gateway (1450)

The Wireless Application Protocol (WAP) Gateway (1450) acts as a normal WAP Gateway service for the monitored device, but also permits recording, blocking, filtering, delaying, redirecting or modification of WAP requests from, and associated responses to, the monitored device. The WAP Gateway service used by the device is specified for the monitored device by the Device Discovery and Modification Module, described below, as part of its normal modification of the mobile device's configuration, policy and provisioning settings. The WAP Gateway (1450) in some exemplary embodiments performs all normal WAP gateway services for the monitored mobile device. In other exemplary embodiments, the WAP Gateway (1450) passes those WAP messages that are not blocked or filtered, optionally after recording, delaying, or modification, between the WAP gateway service originally configured for the monitored mobile device and the monitored mobile device. Such use of the originally configured WAP gateway service can simplify implementation of the WAP Gateway (1450), and also provide an approximation of expected traffic levels to and from the originally configured WAP gateway service, which reduces detectable influences resulting from the operation of the system of the present invention, thus increasing its stealthiness in covert operation scenarios.

The WAP Gateway (1450) can also be used as a method of covert deployment for modules installed on a monitored mobile device. By redirecting the monitored mobile device's WAP gateway traffic through the WAP Gateway (1450), modules of the present invention can be substituted for, or included with, software being downloaded by the device or device user. This avoids a need for a separate transmission of the modules, and “piggybacks” on a known, expected or otherwise unremarkable network connection. In some scenarios the user can install, or authorize installation of when prompted, the modules, while believing they are desired software or data.

In an alternate exemplary method of specifying the WAP Gateway to be used by a device, a device that accepts WAP Gateway settings in the form of signed WAP Binary XML (WBXML) sent via SMS message can be reconfigured by creating a settings specification in XML, converting it to WBXML and signing the result by methods well understood by those having skill in the art. The signed WBXML is sent to the device via an SMS message. The exemplary device, like many in actual current use (such as those used by TMobile of Olympia, Wash.), accepts signed settings without prompting the device user. Once the settings are accepted by the device, the WAP Gateway specified in the settings will be used, rather than the WAP Gateway previously specified for use by the device. This method of altering the WAP Gateway settings of the device is independent of the existence of the Device Discovery and Modification Module on the device, and can be used as a method of instantiating the Device Discovery and Modification Module in some exemplary implementations as described below.

6.7 Network (1300) and Network Billing

The network (1300) provides communication with a control system (1400) and one or more monitored mobile devices (1100).

A mobile device, such as a cell phone, is typically formed of software, firmware, and hardware adapted to provide communications services over a specific wireless network provided by a specific network operator. This process of forming the relationship between the mobile device and the wireless network is known in the art as provisioning. Typically a network operator provisions the mobile device in conjunction with a subscription to a service contract. The service contract specifies the types of voice and data services available to the mobile device user and the charges associated with the use of those services. In some instances, users form a temporary relationship with a service provider using “prepaid” mechanisms that effect payment without a formal service contract.

In a voice and data wireless network such as GSM (Global System for Mobile Communication) and GPRS (General Packet Radio System), CDMA (Code Division Multiple Access), or various other third generation networks such as EDGE (Enhanced Data rates for GSM Evolution) or UMTS (Universal Mobile Telecommunications Systems), both voice and data services may be available to mobile devices. Example voice services include voice calling and Short Messaging Service (SMS). Example data services include Internet browsing, email, and Multimedia Messaging Service (MMS).

Although many services may be available on a given network, only those device users that use mobile communications devices that have been provisioned for those services will be able to benefit from them. This may present problems for the device user and the network operator alike. Network operators provide “free of charge” provisioning services to device users. These services are also called “Type 0” services. Other services are provided by the network operator for managing their network and device configurations. Collectively, type 0 and related network operator-provided management messages are called “carrier reserved protocols”.

Each monitored wireless mobile device (1100) communicates through one or more wireless communications networks (e.g. 1200 a, 1200 b) each of which in turn is in communication with a computer network (1300). Some examples of wireless communications networks (1200 a and 1200 b) include cellular telephone networks utilizing CDMA (Code Division Multiple Access) or GSM (Global System for Mobile communications) technologies including wireless metropolitan or area networks utilizing 802.11-based technologies. The wireless communication networks enable the wireless transmission and reception of information between monitored mobile devices and external control systems. Wireless communications may provide TCP/IP-based protocol support, can provide more limited communications means using SMS, MMS, FLEX, and other messaging protocols. Additionally, wireless communications can provide communications using peered communications mechanisms such as Bluetooth, and can even provide hybrid communications using one or more of the above communications means. Exemplary wireless communications networks (1200 a, 1002 c, and 1200 c) are composed of components having designs, materials, and methods well known to those of ordinary skill in the art.

In some embodiments, the exemplary technology includes a peer-to-peer network connection to a second device, which performs as a proxy between the mobile device and the control system (1400). The alternative technology provides for a proxy device, which can be a mobile device as described herein, a server, or other computer system such as a desktop computer. Alternatively, a network appliance such as a cable modem or set top box may be used as the proxy device. The proxy device provides for control channel and exfiltration information to be communicated to and from the first mobile device via the proxy device instead of communicating directly with the first mobile device. Use of a proxy device is effective for bypassing firewalls and monitoring systems using peer-to-peer networks and protocols.

In one particular implementation, a peer-to-peer network connection can be constructed between the first mobile device (the monitored mobile device) and a second mobile device (e.g. the proxy device) using a peer-to-peer network such as Bluetooth, Infrared, or 802.11 technologies. Other wireless technologies can be used if they are supported by both the monitored mobile devices (1100) and the proxy device. Control information can be passed from the control system directly to the monitored mobile device (1100), or can be relayed through the proxy device. Exfiltrated information can be passed directly to the control system, or can be passed to the proxy device for forwarding to the control system. FIG. 4 shows an exemplary peer-to-peer network connection where exfiltrated information is passed from the monitored mobile device (1100 c) through a 802.11 connection (1200 c) to proxy device (1500), which then forwards the exfiltration information through PSTN/cellular wireless network (1200 d) to network (1300) to control system (1400). Control information also can be passed in the opposite direction through the network from control system (1400) to the proxy device (1500) and then to the monitored mobile device (1100 a).

One challenge for covert operation over commercial networks is masking or removing call detail records associated with telephony and access services provided by wireless carriers. Traditional service agreements provide for wireless device customers to pay charges based upon their usage and to optionally provide call details for all usage of the wireless device against a specific account. Payment arrangements may vary, ranging from monthly subscription, ala carte pricing, prepaid cards, and other commercial schemes implemented by wireless network operators. Various techniques can be used by the present invention to circumvent the accounting and call details that are collected by the wireless carriers.

In a first implementation, the present invention shifts network traffic from a first wireless carrier's network to a second wireless carrier's network. For example, the mobile device may be instructed to route covert messages over a second wireless operator's network where the charges for use of the second wireless network are billed to the control system operator instead of the mobile device user. This can be accomplished by providing alternative device identification numbers that are registered with the second wireless network, or by providing third party billing information to the wireless network provider. Alternatively, the network traffic can be routed to alternate networks, such as WiFi networks if they are in range, where the WiFi network is either not controlled or billed to the mobile device user, or for which alternative billing options have been provided. An example of this technique is to connect to a public WiFi network such as those provided by Earthlink and to connect using an SSID and account that charges the control system operator for use of the WiFi network. Covert traffic may be sent using any of these techniques that eliminate the charges and call detail record reporting to the mobile device user for that covert traffic, having the effect of hiding the traffic reporting on monthly statements.

In a second implementation, covert message traffic may be charged as “type 0” traffic and thus be masked from the device user's bill. In a variant of this tactic, the control system operator may register as a content provider with the wireless network operators, and arrange for usage of their “content service” to be charged to them instead of the mobile device user.

Lastly, for users operating with prepaid services, the control system can automatically replenish funds the mobile device users' prepaid account to compensate the user for use. This technique works because prepaid accounts generally do not provide call detail information to the mobile device users but instead only provide the remaining balance available.

6.8 Monitored Mobile Device (1100)

A monitored mobile device (1100), as described above, can include a cellular telephone, Blackberry, PDA, or other device that communicates using wireless telephony and related data technologies. These devices have a variety of capabilities, including voice telephony, wireless data exchange, applications and capabilities such as Personal Information Management (PIM), camera, Global Positioning System (GPS), and other functions.

A Monitored Mobile Device (1100) is described in greater detail in FIG. 2. A Monitored Mobile Device (1100) includes a Device Operating System (2100) of standard construction known to those having skill in the art, including, for example without limitation, the Windows, Windows Mobile, or Windows CE operating system available from Microsoft Corporation of Redmond, Wash., Unix, Linux, MacOS from Apple, Inc. of Cupertino, Calif., Symbian, Nokia NOS, RIMOS, PalmOS, and NOS (Nokia Operating System). Still other monitored mobile devices may not have an operating system per se, but provide an environment for running Java 2 Micro Edition (J2ME) programs, Binary Runtime Execution Environment (BREW) programs, or similar execution programs and environments. In these cases, the execution environment is considered to be acting as the operating system. Typical monitored mobile devices (1100) include cellular telephones such as those from Nokia of Helskini, Finland and Motorola of Shamburg, Ill., and Blackberry devices from RIM of Waterloo, Ontario, Canada.

A Device Interface (2200) provides a means for converting data to signals compatible with network (1300). The device interface (2200) may implement wired- or wireless communications protocols. An example of one such wired communications protocol is TCP/IP. Examples of a wireless communications protocol include WAP, 802.11x, and equivalent telephony protocols for wireless telephones. The provision of a device interface (2200) to support satellite telephony technology is also contemplated. The selection and management of the device interface (2200) is made under the control of Device Operating System (2100). Each device may be constructed with one or more communications interfaces, which enable the device to simultaneously communicate on multiple networks.

Wireless monitored mobile device client (1120) creates, manages, stores, and otherwise processes collected materials and communicates with server applications (1410, 1420, 1430, 1440), device controller (1490), and other service applications that can be part of control system (1400). The wireless monitored mobile device client (1120) manages and coordinates the operation of the exemplary illustrative technology herein upon the monitored mobile device (1100). The wireless monitored mobile device client (1120) is often referred to herein simply as the “client”. In simplest form, the client (1120) receives messages from the control system (1400) through the communications network (1200), device operating system (2100), and at least one device interface (2200); manages the instructions encoded in the messages, and sends responding messages back to one or more services of control system (1400) containing monitored mobile device information, user responses, additional commands, and collected information (again through the device operating system (2100) and the selected device interface (2200)). In alternative embodiments, the client (1120) acts upon the instructions encoded in the messages and downloads or causes to be downloaded, one or more monitoring modules (collectively modules) that provide additional features and functions to the client (1120). Wireless monitored mobile device client (1120) typically includes a device discovery and modification module (2310), a selective router module (2320), a monitoring information store module (2330), a mobile device control module (2340), and one or more function-specific monitoring modules (2390 a, 2390 b). One or more modules can be assembled together, and one or more modules can be provided as part of a mobile device client (1120).

In one embodiment, the present invention communicates with the client using the well known provisioning mechanisms through which wireless devices interact with host systems. As will be understood by those having ordinary skill in the art, most mobile wireless devices include a capability to be “provisioned”, or to have their software updated, using one or more over-the-air (OTA) methods by which certain messages are reserved for use by the wireless carrier that can cause the device to load module and configuration information without informing the devices user. In some embodiments, the present invention uses such OTA protocols to cause the wireless device to download (or to receive a download) content (modules) to the device without device user notification (i.e., a surreptitious download). The resulting message is accepted by the device as authentic and causes the device to respond as if the carrier had initiated a software load or configuration change. For example, in some embodiments, such surreptitious communications are performed by sending messages to a device that the device accepts as a valid carrier messages. In more specific embodiments such communications are accomplished by adjusting several of the status bits in the message headers, by spoofing return addresses, or by other suitable alterations to the message using methods known to those of ordinary skill in the art.

In one more particular embodiment, the surreptitious communication is accomplished by using SMS messages that are interpreted by systems already installed on the device. In response to properly constructed SMS messages, a target device is instructed to accept software updates, accept changes to device configuration, and many other actions. The present invention includes the use of any suitable SMS message type, including such commonly used SMS message types as WAP Push Service Load (SL) and WAP Push Service Indication (SI) messages. As will be known to those of ordinary skill in the art, SI messages are used to notify the device user that new WAP content is available; SL messages cause the device's browser to load the referenced content, optionally without user intervention. In some embodiments, such SMS messages are designed such that their loaded content includes the device discovery, control modules, or both, of present invention.

6.9 Modules

Modules enable a “pluggable” device monitoring framework that provides system functionality in an extensible manner. Modules facilitate the dynamic addition of new functionality to greatly enhance the flexibility, robustness, and longevity of the system. In one embodiment of the invention, each module is a compiled binary that can be seamlessly OTA deployed into a monitored mobile device (1100) running basic control (2340) and selective router (2320) modules (e.g. the control framework) where the modules are initialized and used by the system. Each specific module can be initiated at any time during the monitored mobile device's life cycle. A module also can be dynamically unloaded from the system for replacement with newer versions or for complete deletion.

Physically a module is provided as a shared library (e.g. a .dll (Dynamic Link Library) in Windows, or a .so or .sl in Linux.) with a known or configurable entry point symbol in some embodiments. In other embodiments, a module can be a standalone executable or a

Java application. The control module (2340) (or other system component) takes care of loading the shared library and initiating module. A single shared library can house multiple application modules if desired, or it might only house a single application module. In some embodiments, the control module (2340), the selective router module (2320), and other functions can be implemented as modules. In this way the entire monitored mobile device management framework can be dynamically updated using the built in mechanisms. Below is a list of the implemented modules for framework and network connection functionality.

6.9.1 Device Discovery and Modification Module (2310)

In some embodiments, the device discovery and modification module are configured to discover the configuration and software present on a specific mobile device, and to load the appropriate selective router (2320) and control (2340) modules to that device. In a first usage, the mobile device (1100) receives a message that causes it to download and run the device discovery and modification module (2310), which in turn performs the following process steps, as depicted in FIG. 5. Often, in such embodiments the message received is a provider service message (such as a type-0 message for provisioning) that causes the mobile device (1100) to download and run the device discovery and modification module (2310). This message can take the form of a required network update message, a provisioning message, or other message type recognized by the mobile device. In devices that support software update or installation through other communication paths, such as via TCP/IP over WiFi, Bluetooth or other connection means, the device discovery and modification module (2310) can be downloaded to the mobile device using such means.

Alternatively, the device discovery and modification module (2310) can be instantiated from an inserted SIM or memory card.

An alternative method for instantiating the device discovery and modification module (2310) on the mobile device involves the use of the WAP Gateway (1450) and WAP Gateway settings alteration method described above. After redirecting a mobile device to use the specified WAP Gateway (1450), any software download initiated by the device user through the WAP gateway, such as a request for a Java application, Active-X control, or other software device, can be intercepted and replaced by or enhanced with a software device that installs the device discovery and modification module. For example, when the user, the browser or other application on the mobile device requests download of a Java “jar” file (a jar file is a transport format used to transmit Java programs and libraries), the requested jar file is replaced by one that downloads and installs the device discovery and modification module when run. The device discovery and modification module downloads the originally requested jar file so that the user, browser or other application obtain the results intended in the original request, and then continues with its other functionality as described herein.

Once instantiated, the device discovery and modification module (2310) first identifies the device's operating system (OS) and capabilities (that is, conducts device discovery for the device) in step S110. The device discovery and modification module (2310) can make service calls to the device's operating system, or can inspect one or more aspects of the device or its communications interfaces, such as files stored on the device or the networks the mobile device is within range of. For example, the device discovery and modification module (2310) can determine the location of the User Agent Profile document information and access that information. In some embodiments, the device discovery and modification module (2310) can cause the device to instantiate a WAP or web browser interface to an external service. Alternatively, the device discovery and modification module (2310) can query the device's operating system to determine specific capabilities of the device.

The device discovery functionality includes, in some embodiments, mobile device capability gathering functionality. In more specific embodiments, this capability gathering provides the device type and capabilities (such as GPS and camera), mobile device operating system information gathering, which yields the device OS ID and version numbers, available memory information gathering, available services gathering, and gathering other device information as necessary. These results are packaged into a response message that is returned to the control system (1400). In some embodiments, the message is targeted to the control service (1410). The message is processed by one or more services of the control system to determine a specific list of modules that can be readily deployed against the specific device. In some embodiments, the device discovery and modification module (2310) then modifies the mobile device's security policy, SMS and OTA provisioning settings to allow the desired device access (step S120). These changes to the device configuration permit the further download and instantiation of modules to the device. The specific changes are implementation specific, however, the following general classes of changes are made:

Security policy—the security policy or policies for the mobile device (1100) are updated to permit module downloads and invocation without user intervention. Specifically, the device discovery and modification module (2310) then modifies the mobile device's security policy to permit the device discovery and modification module (2310), selective router module (2320), and control module (2340) to operate. The device discovery and modification module (2310) also can change or add to the list of approved signing certificates to enable specific monitoring system modules to be downloaded without user intervention. This involves installing a signing certificate into the device and marking the certificate as “trusted”. Software signed using that certificate will then be installable and executable. The exact method for altering the list of approved signing certificates can vary with the operating system type and version. For example, with a Windows Mobile device, the following steps are performed to add a new signing certificate to the trusted certificate store:

-   1. Create a “_setup.xml” file containing an XML description of the     certificate details, including the trust store the certificate is to     be loaded into. -   2. Create a “.cab” file that contains the_setup.xml -   3. Sign the .cab file with a public certificate from a known/trusted     Certificate Authority (e.g. GeoTrust, Verisign, or Thawte). -   4. Install the .cab file on the device.

The XML description in the_setup.xml file has the following general format:

<wap-provisioningdoc>

<characteristic type=“CertificateStore”>

<characteristic type=“Privileged Execution Trust Authorities”>

<characteristic type=“[thumbprint, base64 encoded]”>

<parm name=“EncodedCertificate” value=“[certificate, base64 encoded]”/>

<parm name=“Role” value=“255”/>

</characteristic>

</characteristic>

</wap-provisioningdoc>

The methods used to create the XML description file and .cab file, to sign the .cab file, and to install the file on the device are well known to those with skill in the art.

Signing Certificates are obtained in various ways that depend on the device, the operating system, and/or the device manufacturer. In some cases, such as the Black Berry smart phone from Research In Motion (RIM) of Waterloo, Ontario, Canada, a signing certificate can be obtained by registering with RIM. When the registration information is verified, a certificate is issued. The Symbian OS, from Symbian Limited of London, United Kingdom, and the iPhone from Apple, Inc. of Cupertino, Calif., use a similar method. In some cases a separate Certificate Authority (CA), such as Geotrust, owned by Verisign of Mountain View, Calif., can issue certificates. In other cases, such as J2ME (used on devices from a variety of manufacturers), the code of an application to be signed is sent to the issuing authority, such as the device manufacturer, as is the case with RIM's Black Berry smartphones, which tests the code to ensure that it does what it claims to do, and then issues a signing certificate for the application. In yet other cases, such as Apple's iPhone, the device will only accept software downloads from a particular server, though in some cases arrangements can be made to specify a private server rather than that operated by the device manufacturer. In these and other cases, use of a “trojanized” application is necessary. In this method a signed application is obtained, the certificate removed and additional code added to the application, which is then re-signed as an updated version of the same application.

SMS—the SMS configuration is modified to permit the receipt and processing of SMS messages for the monitoring system without user notification. The SMS system is further modified to hide incoming SMS messages targeted to the monitoring system from the user.

OTA—the OTA provisioning configuration is modified to permit the receipt and processing of OTA downloads without user notification. The OTA provisioning configuration can be further modified to extend the list of “trusted” locations from which the device can download modules OTA.

The device discovery and modification module (2310) then loads any required digital certificates to the mobile device (step 5130). Most mobile device software is signed by the manufacturer, and the software designed for the device must be digitally signed using an approved signing certificate in order for the software to load. In some embodiments, the modules to be downloaded into the mobile device are signed using a commercially approved signing certificate. In other embodiments, the modules are signed using a different signing certificate. A mobile device typically stores copies of the signing certificates required to validate module digital signatures in its certificate store. The device discovery and modification module (2310) checks the mobile device's certificate store to ensure that all required digital certificates are present in the certificate store, and adds any additionally required certificates to the certificate store. Optionally, the device discovery and modification module (2310) further checks the device date and time to ensure that the device's date/time is within the valid range of the installed certificates. This optional step can permit new modules to be loaded without causing the device operating system (2100) to generate an exception when new modules are loaded. The digital certificates to be loaded into the certificate store can be included within the device discovery and modification module (2310), can be separate from the device discovery and modification module, but packaged with it for delivery to the device, or can be independently downloaded from the control system (1400). In some embodiments, the download source is the module repository (1420).

The device discovery and modification module (2310) then accesses the device's data connection (step 5140). The device discovery and modification module (2310) first identifies the mobile device interfaces (2200) and the networks to which the interfaces are connected, and attempts to determine available network paths between the mobile device (1100) and the control system. For example, the device discovery and modification module (2310) identifies whether a mobile device's interfaces include an 802.11 interface, and if they do, determines if the 802.11 interface is enabled and within range of an 802.11 network. In some embodiments, the device discovery and modification module (2310) contains preferred 802.11 SSID's and authentication materials that allow the device discovery and modification module (2310) to establish an 802.11 network connection to well known 802.11 networks such as those provided by a commercial hot spot provider such as Boingo®, of Boingo Wireless, Inc. of Santa Monica, Calif.

The device discovery and modification module (2310) then selects and secures a method of communication with the control system (1400) (step 5150). This step uses information collected above in step 5140 as a starting list of available networks. The device discovery and modification module (2310) attempts to connect to one or more services of the control system (1400), using one or more of the following protocols: SMS, IM, HTTP, FTP, WEP or email. The results of these attempts indicate the preferable approach to load and instantiate additional modules to the mobile device (1100).

The device discovery and modification module (2310) then loads (or causes to be loaded) the appropriate selective router module (2320) and control module (2340) on the device (step 5160). The device discovery and modification module (2310) then loads other modules as appropriate for the mobile device. In some embodiments, the device discovery and modification module (2310) requests specific modules from the control system, in particular, from a module repository (1420). In other embodiments, the device discovery and modification module (2310) requests the modules appropriate for a particular device from a control system service and the control system service selects the modules to be downloaded based upon the device discovery information (see above) and/or operator specification. In a particular embodiment, the module repository (1420) uses the device discovery information to determine the modules to download, and makes these modules available to the device discovery and modification module (2310) for download. The device discovery and modification module (2310) then downloads the modules and instantiates them on the mobile device (1100).

The device discovery and modification module (2310) then deletes itself and passes control to the control module (2340) (step 5170), which ends the process. By implementing these functionalities, the device discovery and modification module (2310) allows successful loading of further monitoring and control components of the present invention. The device discovery and modification module's functionality is limited and specific; thus the module has a small footprint, is stealthy, can remove itself, and covers a wide range of devices.

6.9.2 Selective Router Module (2320)

Referring back to FIG. 2, a selective router module (2320) is responsible for monitoring one or more communications interfaces (e.g. 2210, 2220, & 2230) of the monitored mobile device (1100) and manages communications over the selected communication interfaces. In some embodiments, the selective router module (2320) additionally monitors specific message types, such as SMS. The selective router module (2320), in a first aspect, functions as an interface proxy service, in that the selective router module (2320) inspects incoming and outgoing network traffic on each monitored network interface and messaging method, and makes determinations as to how to process this traffic. Typically the selective router module (2320) intercepts and manages message communication via multiple protocols such as WAP, HTTP, HTTPS, SMS/MMS, TCP, UDP and USSD.

In some exemplary embodiments, the selective router module (2320) is installed such that it retains the ability to monitor and control specified incoming and outgoing network traffic even after a monitored mobile device (1100) is rebooted. In some devices this can require that the selective router module (2320) is loaded before other software that is installed on the device, while in other devices the selective router module (2320) can be loaded after other software, but prior to any incoming or outgoing network traffic being received or sent. Techniques for accomplishing this requirement are well known to those with skill in the art. For example a first method comprises replacing existing device communication software modules with those of the selective router module so that the selective router module is automatically loaded during device startup and used by the device operating system or other software to perform communication activities, and thus given access to all device communication data. In a more specific example, the Windows Mobile OS incorporates a mechanism, known as the Radio Interface Layer (RIL) that handles communications between the Windows Mobile system software and the device's radio hardware. The RIL abstracts the details of the hardware components, which can vary between a first device type and a second device type, and provides a common known interface to the hardware for the operating system and other software to use. The RIL, which is implemented as a Dynamically Linked Library (DLL), can be replaced with a custom DLL of an exemplary embodiment of the current invention. Provided that the custom DLL implements the same software interface functions as the RIL provides, the operating system and other software will continue to function normally. The custom DLL implements the RIL functionality in some exemplary embodiments, while in other exemplary embodiments the custom DLL uses the capabilities of the replaced RIL DLL rather than implementing them itself. By taking over the RIL's position as the initial recipient of requests for RIL functionality, the custom DLL is used by all subsystems of the Windows Mobile device and is in a position to intercept all incoming and outgoing Short Message Service (SMS) data and can block, modify, filter, log, relay, or permit to pass intact all such data.

In a second example method, the device hardware is reconfigured to invoke aspects of the selective router module when data arrives at the device's communication interface, and the device operating system data structures are modified such that requests to send data from the device result in the data being passed to the selective router module, rather than the aspect of the operating system that would normally perform the operations necessary to send the data.

In a third example method, the device configuration is modified so as to link the selective router module into the normal device communication data flow using functionality present in the device or device operating system. For example, in a Windows Mobile device, the selective router module can be installed as a Windows service, and will be loaded by the operating system each time the device is booted. This is accomplished by installing required registry keys:

-   -   HKLM,Services\OEService,D11, 0x00000000,name.dll     -   HKLM,Services\OEService,Prefix, 0x00000000,0ES     -   HKLM,Services\OEService,Order, 0x00010001, 10     -   HKLM,Services\OEService,Keep, 0x00010001, 1     -   HKLM,Services\OEService,Index, 0x00010001, 0

Selecting an innocuous name for the DLL file can reduce the likelihood of suspicion about the service. For example, “IO.dll”, or “system.dll”.

In a fourth example method, the selective router module monitors message storage locations and acts on any messages that are added to them. For example, the Symbian OS uses SMS storage mailboxes for incoming text and service load or WAP push messages, as well as outgoing text messages sent by client applications on the device. By monitoring and acting on any messages that appear in these mailboxes, SMS traffic can be filtered, blocked, monitored and otherwise controlled.

When a device supports more than one method of intercepting, controlling or blocking communication, such as replacement of a dll and redirection of hardware pointers, a plurality of methods can be used, with different methods used for each communication method supported by the device, or a plurality of methods can be used at once to deal with a given communication method. The preferred method for a given device will be apparent to one skilled in the art.

In any of these examples, the selective router module can make use of the device modules that are replaced or superseded to perform the actual data reception and/or transmission, once the data has been logged, modified, or otherwise processed in accordance with the design of the selective router module. This permits the selective router module (2320) to filter, block, store, modify or otherwise process network traffic prior to or instead of the network traffic being processed by any other device software or by any device hardware other than that required to deliver the traffic to the selective router module (2320). On mobile devices built using Microsoft Windows, the boot order is determined by class IDs. Where the selective router module appears in the boot order is based on the selective router module's class ID, when the selective router module is implemented as a separate process. FIG. 6 depicts some different ways in which the selective router module (2320) can interact with network traffic.

In addition to communication between a device and external devices and systems, communication can also take place between a SIM card and the device the SIM card is inserted into (referred to herein as a “handset”). In some cases such communication is initiated by messages sent from external devices and systems to the SIM card, while in other cases the communication is initiated by the SIM card or by applications running on the SIM card. To maintain control over the device, the selective router module must be able to block, modify, filter, log or permit such communication between handset and SIM card. Methods similar to those used to intercept and control external communication are applicable to the handset/SIM card communication; including replacement of aspects of the handset operating system, such as DLLs, and reconfiguring hardware to interface with aspects of exemplary implementations of the current invention rather than with the existing device software. For example, The Symbian OS comprises a capability referred to as the “Etelsat Layer”, which deals with communication between the system software and the device's radio hardware. Within the Etelsat Layer, the RSat Interface provides handset software access to SIM Toolkit procedures that exist on the SIM card. This access is given to all applications, so there is no need to replace the layer with a custom one. The SIM Toolkit procedures permit an application to see Short Message Service (SMS) messages and proactive communications between the handset and SIM.

The capability to selectively block or modify network traffic entering or leaving the device can be used to protect the selective router module (2320) and other modules and stored data from interference by software updates that are performed using network downloads. When such a download is detected, the download can be analyzed by the selective router module in some exemplary embodiments, and in other exemplary embodiments the download can be redirected to the control service for analysis by automated systems and/or human operators. If the download is determined to be harmless to the selective router and other modules and data, it can be permitted to be processed normally by the device. If the download is determined to be of a nature that would remove, disable, or otherwise interfere with the operation of the selective router or other modules or data, such as an anti-virus system update that includes detection capabilities for the selective router or other modules or data, a patch to the operating system that would remove the selective router by overwriting it with new software, or a utility program that reports data that could indicate the presence of the selective router module or other modules or data, the download can be blocked, or be substituted with an alternate download that does not remove, disable or otherwise interfere with the operation of the selective router or other modules or data.

Additional methods for avoiding disablement or removal of the selective router module and other components and data used by the invention, include removal of the selective router module and other components from operating system “uninstall lists’ (i.e. lists of software that has been installed, which are used to prompt the user for selections of software to be removed), and removal of the selective router module or other components from displays of running processes. In some devices, such as those running the Symbian OS, there are features, such as the Symbian OS “recognizer”, that can be configured to restart the selective router module or other components if they cease operating for any reason.

In at least some devices it is not possible for the selective router module to remain functional after a device is reset to a factory initial state. Where the selective router module can not intercept, block and simulate such a reset to convince the user that it was performed when it was not actually performed, it is necessary to reinstall the selective router module and other modules and settings, for example, using one of the methods described above.

In a first embodiment, the selective router module (2320) notes the message traffic (6200) and uses the fact that there is a particular type of network traffic to update the operations (6210) of the selective router module (2320). For example, if the selective router module (2320) notices that there is 802.11 (that is, WiFi) network traffic, the selective router module (2320) updates its internal tables to indicate that the system is currently connected to an 802.11 network. This can be used to trigger additional functionality of the module, as described below.

In a second embodiment, the selective router module (2320) captures copies of the network traffic (6300) and stores these copies in the storage module ((2330), described below) for subsequent exfiltration. The selective router module (2320) can filter or otherwise limit the amount of network traffic captured. The filtering can be performed based upon size, destination, source, contents, or other attributes of the network traffic.

In a third embodiment, the selective router module (2320) monitors and redirects network traffic targeted to specific modules of the present invention. For example, a selective router (2320) can monitor the SMS received queue (6110) and extract SMS messages (6400) targeted for the control module (2340), and then deliver these SMS messages directly to the control module (2340) without further interaction being required by the monitored mobile device operator. The selective router module (2320) also can delete any user visible references to SMS messages targeted to the control system and prevent these messages from being seen by any other user or process. This includes deleting or hiding copies of the message in system queues and notifications. This permits the modules to receive network messages without interrupting the monitored mobile device operator. In an alternative example, a TCP/IP intercept (6500) can receive network traffic (6120) returned to an application on the monitored mobile device (1100). However, the TCP/IP traffic can have a covert payload destined from one of the modules on the monitored mobile device (1100). The selective router module (2320) removes the covert payload (6510) from the message, forwards the message (6520) without the covert payload to the intended destination (1110 a), and forwards the covert payload (6530) to the appropriate module (2390 a) for processing.

In a fourth embodiment, the selective router module (2320) intercepts network traffic sent from an application (1110 b) on the monitored mobile device (1100). In this example, the network traffic is an HTTP request to a particular web server on the network. After intercepting the network traffic (6600), the selective router module (2320) rewrites the request (6620) to forward the request to a service that is part of the control system (1400), and optionally appends a covert payload (6610) to the request. This technique is useful for covertly transmitting monitoring information to the control system embedded within other network traffic. In some embodiments the control system (1400) can optionally embed commands or other data in responses to requests, such as HTTP acknowledgement messages, or TCP/IP headers. Various techniques for including the covert payload in the message traffic can be used, including embedding encrypted payloads, adding attachments to mail messages, steganographic methods for information hiding, and other techniques well known to those skilled in the art. In some embodiments, the covert payload can be encrypted.

In a fifth embodiment, the selective router module (2320) encrypts and decrypts network traffic sent between a monitored mobile device and a control system (1400). In some embodiments, commands sent by the control system to a mobile device are SMS based, and are sent either to the default SMS port or to the specific port identified during the post installation step. Complete commands may span multiple SMS messages. In other embodiments, other messaging mechanisms such as TCP/IP sockets, or Bluetooth connections can be used.

In some embodiments, communications between the control system (1400) and the monitored mobile device are encrypted, for example by using a standard symmetric key encryption algorithm such as AES, triple-DES, or other general purpose symmetric key encryption algorithm supported by both the device and the control system (1400). In one particular embodiment, the encryption key selected is the device's IMEI number. If the key is less than 16 characters in length, the key will be padded with ‘$’ to 16 characters. If the key is greater than 16 characters in length, then the key is truncated to 16 characters.

Commands and modules downloaded from the control system (1400) to the device are encrypted using the specified encryption algorithm, the encrypted results are then optionally encoded using a transport-encoding mechanism such as Base64, and then segmented to fit within the selected network transport. After segmenting the message, the unique device ID is prepended to the each message segment to allow the messages to be appropriately managed by the receiver. Similarly, responses from the mobile device are also optionally encrypted and encoded as described above. Exfiltrated information is similarly encrypted and encoded as necessary.

The selective router module (2320) also is able to recognize when specific network interfaces are enabled and connected to a network and when monitoring information can be exfiltrated from the monitored mobile device (1100) with a minimum chance of detection. The selective router module (2320) can select the routing of the exfiltrated messages (e.g. between an 802.11 network and a GPRS network), and then package and route materials over the selected network(s) using preconfigured defaults and access information. In some embodiments, the selective router module (2320) uses authentication materials that allow the selective router module (2320) to establish an 802.11 network connection to a commercial hot spot provider such as Boingo® by associating a well known SSID with the authentication materials. In other embodiments, the authentication materials can be downloaded to the monitored mobile device (1100) after the available networks are identified. Without limitation, the selective router module (2320) can utilize any network interface available to the monitored mobile device (1100), such as infrared, Bluetooth, or other point to point networks. When operating in conjunction with a proxy device, the selective router module can route specific types of network traffic to the proxy device by routing messages to the proxy device over an alternate peer-to-peer network interface, such as Bluetooth or peer-to-peer WiFi, and the proxy device forwards the messages to the control system.

Additionally, the selective router module (2320) can identify network connections that are blocked by firewalls or do not provide access to the control server and route traffic away from these networks. In some embodiments, firewall identification is performed by monitoring network traffic to and from the monitored mobile device, for example, monitoring traffic to and from a mobile browser application or to and from the network provider. Alternatively, the selective router module (2320) can probe the network to determine if a network path is open and available. In some embodiments, the probe may take the form of a Web request to a third party, such as a request to the Microsoft Software update site. If the request is completed correctly, the selective router module (2320) is able to use this information to determine that the tested network path is probably not blocked by a firewall. The above example illustrates the covert probing of a network using requests that appear “normal” to an observer but return useful information to the selective router module (2320).

In some exemplary embodiments, the selective router module (2320) is constructed or configured so as to use a particular method or methods to route exfiltrating data from the monitored device. Such particular method or methods can be the same for all devices, preselected by device type, pre-selected based on specific sets of characteristics of a particular device, or selected on a device by device basis using automated systems that use a plurality of factors, such as device type, device features, anticipated data volumes, required level of stealthiness, available methods of accepting exfiltrated data from monitored devices, or others.

In exemplary embodiments where the selective router module (2320) is configured, rather than constructed, to use a particular method or methods to route exfiltrating data from the monitored device, the configuration data can be installed with the selective router module (2320) or installed, or reinstalled, separately from it. In exemplary embodiments where the configuration data is installed separately, the selective router module (2320) is typically designed with a default configuration to use in the absence of such configuration data to prevent failure if the configuration data is lost or is delivered after the selective router module (2320) is activated.

In some other exemplary embodiments, the selective router module (2320) is constructed and configured so as to choose a method to use to route exfiltrating data based on factors such as the capabilities of the device, the type of data to be exfiltrated and the current device communication state. For example, if the device has Wi-Fi capability, is located in a Wi-Fi hotspot, and is currently transmitting and receiving data over Wi-Fi, the selective router module (2320) can choose to exfiltrate data over Wi-Fi. At another time the device might have the capability and connectivity to send SMS messages, but not be located such that a Wi-Fi connection is possible and the selective router module (2320) can choose to exfiltrate data appropriate to sending over SMS, but retain other data which is not appropriate for SMS exfiltration until a Wi-Fi connection is possible. The selective router module (2320) can optionally be designed or configured with parameters that give preference to particular methods over other methods. As will be apparent to those with skill in the art, such a weighted selection procedure, whether based on the type of data or on other factors, can be extended to any network path or Peer-To-Peer connection that a device is capable of using, such as GPRS, Bluetooth or IrDA.

In some exemplary embodiments, the selective router module (2320) can detect and monitor the rate that data is being sent by the monitored device due to user activity, and limit its own exfiltration data rate in proportion to the monitored user activity data rate so as to be less likely to attract the device user's notice. In some exemplary embodiments, the selective router module (2320) can notify the Device Controller (1490) or other appropriate system component, of the monitored device's incoming data rate, so that transmissions to the monitored device can be limited in proportion as well.

As shown by the flowchart depicted in FIG. 7, in one exemplary procedure for choosing a network path for exfiltration of data, the selective router module (2320), first identifies available network paths (7110). Such identification can be a specific action or series of actions, such as querying the device's operating system, reading device hardware state, or it can be done incidental to the selective router module's other functions, such as acting as a proxy for monitored device user activities. The selective router module (2320) then identifies which of the available network paths is currently in use, and calculates the data rate for each (7120). The types and amount of data waiting for exfiltration is then compared to the available network paths and their data rates (7130) to select a network path for the waiting data to be sent over. Criteria for matching data to network paths and data rates can be designed into the selective router module (2320), or they can be set by configuration parameters which are read by the selective router module (2320). In general, matching will select, or even require, higher bandwidth network paths for data types such as sound or image data, that typically involve large amounts of data, and select higher bandwidth network paths over lower bandwidth network paths, to limit the duration of transmissions and thus reduce the chance of the transmissions being noticed. If there is no network data path that matches the waiting data (7140), the process terminates, no network path is selected, and the data continues to wait for exfiltration. If there is a match found, the data that matches, which may be all or less than all, of the data waiting for exfiltration, is sent using the matching network path, at a rate that is proportional to the rate that the network path was already sending data (7150). Once the data has been sent, if there is more data to send (7160), the process repeats starting with a re-check of available network paths (7110), in case this has changed, otherwise the process terminates.

The selective router module (2320) can include additional factors in calculating when to exfiltrate data, which network path to use, and what technique to use for exfiltrating data over the selected network path. Such additional factors can include:

-   -   A send buffer becomes full.     -   When cache space reaches a specific level (e.g. 80% used).     -   When there is any data at all to send (i.e. send as soon as         possible, don't cache).     -   When the device is sending other (non-exfiltration) data. (i.e.         when the exfiltration data can blend in with normal data traffic         flows).     -   Send at least once in every specified interval of time (e.g.         send once an hour, once a day, etc.).     -   Send at specific times (i.e. 3 am, 7:20 pm, etc.).     -   Send when located in particular cell coverage areas.     -   Prohibit send if located in particular cell coverage areas.

Additional factors can be combined in some exemplary implementations. For example, a selective router module (2320) could be designed or configured to send data when cache becomes 50% full, there is normal device traffic being sent, and the device is located in particular cell coverage areas. A plurality of conditions can also be defined. For example, a device can be designed or configured to send when cache reaches 50% of capacity and normal device traffic is being sent, but if cache reaches 80% full, sending can occur even if there is no normal device traffic being sent.

6.9.3 Monitoring Information Store Module (2330)

The monitoring information store module (2330) provides a hidden storage for collected monitoring information prior to exfiltration. In some embodiments, the monitoring information store module (2330) varies based upon the amount of information being stored, whether the information must be hidden from the user of the monitored mobile device (1100), and the type of device the information is stored on. Table 2 lists the service operations provided to other modules operating on the monitored mobile device (1100) by the monitoring information store module (2330).

TABLE 2 Monitoring Information Store Module Service Operations OPERATION ACTION Create collected monitoring Creates a set of collected monitoring information information, establishing any necessary information hiding, obfuscation, or encryption techniques that might be required. Add to collected monitoring Adds collected information to a set of information collected monitoring information. Delete collected monitoring Deletes a specified set of collected information monitoring information from the monitored mobile device. List collected monitoring Lists the collected monitoring information information stored on the monitored mobile device. Store data on device Stores a specified set of monitoring information on the monitored mobile device. Transmit stored data Transmits stored data from the monitored mobile device to the control system.

In more specific embodiments, the monitoring information store module (2330) monitors the amount of stored information on the monitored mobile device (1100) to prevent the device from being completely filled by the collected monitoring information. If the amount of storage used on the monitored mobile device (1100) reaches a first threshold, the monitoring information store module (2330) notifies the control module (2340) that the device is becoming full, and that collected monitoring information should be exfiltrated in order to prevent the data from becoming lost. If the amount of storage available on the monitored mobile device (1100) reaches a second threshold, the monitoring information store module (2330) deletes some or all of one or more collected monitoring information sets. Alternatively, the monitoring information store module (2330) can compress one or more sets of collected monitoring information. In still other embodiments, the monitoring information store module (2330) can move one or more sets of collected monitoring information to alternative storage (such as the SIM card) if the alternate storage is available.

In some embodiments, the monitoring information store module collects similar information together for ease of storage or exfiltration. The collected information is called a database, even through the internal data structure can be one of a database, a e-mail box, a flat file, a compressed archive, or other storage mechanism appropriate for the device and data type. Example of types of information grouped together include: SMS messages in an SMS database, e-mail messages in an e-mail database, call details in a Call Detail Record database, and the like.

In some embodiments, the monitoring information store module (2330) uses obfuscation techniques to hide the monitoring information from users of the monitored mobile device (1100). These obfuscation techniques are well understood to those skilled in the art, and may include such techniques as:

-   -   Hiding files in directories     -   Using hidden file names (for monitored mobile device (1100)         operating systems that support hidden file names)     -   False or misleading naming of files     -   Naming files with unprintable/unreadable names

The monitoring information store module (2330) also can protect one or more pieces of monitored information using standard encryption and/or digital signature techniques well known to those skilled in the art.

6.9.4 Control Module (2340)

In still other embodiments, the Control module (2340) communicates with Control Services (e.g. Control Service (1410) of the control system (1400)). In some embodiments, the control service uses the services of a separate selective router to communicate with a Control Service. In other embodiments, features of the selective router are combined into the control module for efficiency. The control module (2340) manages the deployment and operation of the modules, including the update of existing modules and the deployment and operation of monitoring modules. The control module (2340) operates under the direction of one or more Control Service(s). In a first embodiment, the control module (2340) downloads and loads modules onto the monitored mobile device (1100) as commanded, communicates status with control servers, tracks device memory, deletes modules as commanded, detects debugging and deletes files and components, and can self destruct if required. After the control module is installed, communication with the control system (1400) is made to receive the Device ID that uniquely identifies the device the control module is installed on. This request may be made in an SMS, HTTP GET or POST, or other format. As will be understood by persons having ordinary skill in the art, although each request parameter is not strictly required, the more info that is provided, the better the control system (1400) is able to uniquely identify the device. In more specific embodiments, the control system (1400) stores the values provided in its internal data store and generates a Device ID. The Device ID will be used for identification purposes in all future communication from the device to the control system (1400).

The control module (2340) monitors the status of the device's SIM card, or SIM card equivalent to detect replacement of the SIM card. This can be accomplished by means such as the device making a “Refresh” request to the SIM card, to cause the SIM card to notify the device of any changes in SIM files. An alternative method for detecting a replacement of the SIM card in a device involves use of an application on the SIM card that makes unusual regular requests to the device that are not apparent to the device user, such as setting up an “event list” or initiating a particular Proactive SIM command. If these unusual regular requests are not seen, the device uses this as an indication that the SIM has been replaced by a new SIM. Those of skill in the art will know of yet other methods of detecting SIM replacement in a device.

If a first SIM card is replaced by a second SIM card in a first device, the control module on the first device obtains the ID information from the second SIM card, and sends this to the control system (1400), which updates the stored information for the first device. In scenarios where the first SIM card was used to instantiate the device discovery and modification module, insertion of the first SIM card into a second device can result in the second device instantiating a device discovery and modification module that contacts the control system (1400). In such cases the control system (1400) can instruct the second device's device discovery and modification module to remove itself without installing any additional components on the second device if monitoring of the second device is not desired. Alternatively, the control system (1400) can store the second device's information and begin monitoring the second device too.

In a first usage, the control module (2340) receives an incoming message from the control service (1400) or the selective router (2320), parses arguments from the message and invokes requested instruction, and reports status of instruction processing to the control system (1400). The messages from the control service or selective router have a specific header format as shown in Table 3.

TABLE 3 General Server Initiated Command Parameters (“I” delimited) MIN MAX OC- OC- NAME DESCRIPTION TYPE CURS CURS # AES The very first character is the Hex 1 1 Pad char- Hex representation of the Numeric acters number of pad characters appended to the encrypted message. This number is used to strip off the AES padding at the end of the message. This parameter is not delimited from the SMS # parameter. SMS # This represents the position HEX 1 1 this SMS is in respects to any Numeric other SMS that may make up the command. The first SMS is 0 and if the message is too big for one SMS, then next SMS will be 1. If the SMS number is greater than 0, control module headers will be shortened. There will only be SMS#, Message ID, then a payload in SMS's after the first SMS. This payload will need to be concatenated to the prior SMS payload Protocol Version of the control module Hex 1 1 version header fields. This lets the Numeric device know the scheme of the control module header fields. Number Number of SMSs that make Hex 1 1 of Total up the entire command. If Numeric SMS the message is too big for one SMS, this value tells you how many total SMS's to watch for. Minimum is 1.

Application IDs are assigned at the time application modules are built. The control module application has a value of 0. “Ctrl + k” delimiter Command The control module Static 1 1 command. Possible values are listed below. Each of these is discussed in more detail in a later section sd—Set Destination im—Install Module um—Update Module dm—Delete Module mi—Module Inventory mq—Memory Query da—Destroy All me—Module Command

Once decrypted, the text of the message contains header information for the control module and application module specific instructions. The message is in delimited ASCII encoding, using “ctrl-k” and “I” as delimiters. The selection of delimiter characters and encoding character set is implementation dependent. In this example embodiment, the header information is separated by “Ctrl+k” character. Each of the parameters are delimited by a pipe (l). The elements within the delimited string are parameters that define the meaning of the command. Additional parameters then may be appended for commands sent to specific modules. The meaning of these additional parameters is not necessarily known to control module. It is expected that the module being commanded will understand the parameters. The control module will always pass these values through to the module without modification.

The Control module acknowledges receipt and provides processing status for each command it receives. Additionally, the device may periodically transmit messages to the control system (1400) based on trigger events that may occur on the device (i.e., incoming SMS message, incoming phone call, device shutdown/startup, etc.). An example format for these messages is illustrated in Table 4. All messages are sent to the control system (1400) using the protocol and remote address identified via the Set Destination process (see section 5.8.4.1.6). Response messages are formatted and optionally encoded and/or encrypted as described elsewhere.

Each application defines its own set of ReturnCode values. ErrorString A string containing a Alpha 0 1 description of the error(s) that Nu- occurred during processing meric

The incoming message includes one or more instructions to the control module (2340). The first portion of the instruction includes a ‘Control’ instruction that the control module (2340) can process. Exemplary control instructions include those shown in Table 5. The function of each of these control instructions is described in more detail in the sections below.

TABLE 5 Control Instructions CONTROL INSTRUCTION ACTION Set Destination (sd) Sets the default destination for exfiltration requests Install/Update Installs or updates a module. (im/um) Uninstall (dm) Deletes a module. Inventory List (mi) Reports the inventory of installed modules. Memory Query (mq) Queries available memory on the monitored mobile device (1100). Self destruct (da) Destroys all modules and data on the monitored mobile device (1100). Command (mc) Passes a command to an installed module.

Various portions of the message define the instruction processing status callback address, which is the service address to be used by the control module (2340) (or another module) to access a control service (1400). This service address defines the protocol and destination endpoint for processing responses from a mobile device to a control service. The instruction processing status callback address can be an SMS address, a USSD address, or a service address defined by UDP, TCP, or URI address. Example instruction processing status callback addresses include those shown in Table 6.

TABLE 6 Instruction Processing Status Callback Address Examples PROCESSING STATUS CALLBACK ADDRESS TYPE ADDRESS SMS specification sms://<msisdn> e.g. “SMS://3105551212” USSD specification ussd://<ussd string>,e.g. “USSD://*#555#” UDP specification udp://<ip>:<port>,e.g. “UDP: 10.1.1.1:2000” TCP specification tcp://<ip>:<port>, e.g. “TCP :10.1.1.1:2000” URI specification “HTTP:10.1.1.1:2000/path/to/service” (in the form specified by RFC 3986) 6.9.4.1 Control Module Commands

The following sections describe the control module functioning in response to various commands.

6.9.4.1.1 Install Module Command

The Install Module command allows the control system (1400) to instruct the control module to load new modules onto the device via the control module application. A message (header portions truncated for clarity) specifying the control parameters below is received by the control module and processed.

TABLE 7 Install Module Command Parameters (“I” delimited) MIN MAX OC- OC- NAME DESCRIPTION TYPE CURS CURS . . . header omitted for clarity Application 0 (control module) Hex 1 1 ID Nu- meric “Ctrl + k” Command im (Install Module) Static 1 1 Target The unique identifier for the Hex 1 1 Application application being installed. Nu- ID Application IDs are assigned at the meric time application modules are built. The control module application has a value of 0. URI The URI where control module can Alpha 1 1 download the target application. nu- meric

Upon receipt of the Install Module command, the control module causes the defined application to be loaded from the specified URI using the access method and parameters specified in the URI. The loaded control module is installed into the mobile device, and assigned the “target application ID” provided in the control message (see above).

An example of a textual version of an install command received by a mobile device is shown below. The example uses “ctrl-k” and “l” as delimiters, and is shown without encryption, base64 encoding, or other adjustments. It provides an example of how the parameters described for a specific command are encoded for transmission over a textual transmission mechanism such as SMS. Other encodings are possible within the scope of the invention and may be performed by those skilled in the art.

The Set Destination command allows the control system (1400) to configure the bearer, protocol and remote address the control module application sends messages to. Each module installed on the device (as well as the control module application itself) can have its own destination configuration, and each destination configuration can have a list of distinct remote destinations. Each remote destination has associated with it a priority. The control module application first attempts to send messages using the highest priority destination available. In the event of a failure, the control module application falls back to the next highest priority, and continues until the send is successful or the list of destinations is exhausted. Additionally, if a particular module does not have a destination configuration defined, the control module application uses its own destination configuration.

The Camera module captures still images or video (with or without audio) from the monitored mobile device's camera, if an image or video capture capability was identified on the device. In some embodiments, the camera module is configured to take one or more images from the camera, on a command or timed basis as well as when specified events occur, such as on device startup, when there is an incoming phone call, when the device changes location, etc. These images are exfiltrated to the control system (1440). The methods of video capture are configurable and include the following:

-   -   Capture and store images     -   Capture and store video     -   Events to capture images     -   Events to capture video     -   Relay stored images or video, whether taken with the camera or         just stored on the device     -   Relay during capture (streaming)     -   Image or video quality specification

The recorded images or video can be immediately streamed to the control system (1400), or saved on the device for later upload.
